Product details
Overview
LMV712Q1MMX/NOPB from Texas Instruments is a dual rail-to-rail input/output operational amplifier with independent shutdown control, designed for power amplifier control loops in RF front-ends. It delivers 5 MHz gain-bandwidth, 5 V/µs slew rate, 20 nV/√Hz input voltage noise, 1.22 mA/channel supply current, and operates from 2.7 V to 5.5 V across –40°C to +125°C.
For engineers reviewing the LMV712Q1MMX/NOPB datasheet, LMV712Q1MMX/NOPB pinout, LMV712Q1MMX/NOPB application, or LMV712Q1MMX/NOPB equivalent, key selection criteria include independent channel shutdown timing (2.2 µs turnon), rail-to-rail output swing into 600 Ω (4.82 V at 5 V supply), low input offset voltage (≤3 mV), and AEC-Q100 Grade 1 qualification for automotive RF subsystems.
Technical Context
The LMV712Q1MMX/NOPB integrates parallel NMOS and PMOS input stages to achieve rail-to-rail common-mode input range, with internal logic dynamically allocating bias current between stages based on VCM. Its output stage uses a PMOS–NPN composite configuration to deliver true rail-to-rail output swing while maintaining stability with up to 200 pF capacitive load in unity-gain configuration.
Independent SDA and SDB pins enable per-channel shutdown, reducing supply current to ≤1.5 µA per channel and forcing outputs to V− during disable. The device features glitch-free output ramp-up during wake-up-critical for GSM/UMTS power amplifier envelope control where output transients directly modulate RF output power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5 MHz - supports stable closed-loop operation up to 100 kHz with ≥60° phase margin in PA control feedback paths |
| Slew rate | 5 V/µs - enables fast response to dynamic envelope signals in GSM/EDGE burst transmission |
| Input voltage noise | 20 nV/√Hz at 1 kHz - minimizes added noise in low-level detector and coupler signal conditioning |
| Supply current per channel | 1.22 mA (typ) at 2.7 V - enables battery-operated portable RF modules with dual-opamp signal chains |
| Shutdown current | 1.5 µA (max) per channel - allows deep power gating of unused amplifier channel without PCB redesign |
| Output swing (RL = 600 Ω) | 4.82 V (min) at V+ = 5 V - ensures full-scale drive capability into typical PA bias networks |
| Common-mode input range | V− − 0.2 V to V+ + 0.3 V - accommodates direct sensing of RF detector outputs near ground or supply rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail opamp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722Q1MMX/NOPB | Higher 10 MHz GBW, 8 V/µs slew rate, but no shutdown function; 1.5 mA/channel supply current | Lacks independent shutdown-unsuitable for burst-mode PA control requiring glitch-free wake-up | Select when higher bandwidth is critical and shutdown is managed externally via power sequencing |
| TLV9062IPWR | Lower 10 nV/√Hz noise, 1.2 mA/channel, but only 10 V/µs slew rate and no AEC-Q100 qualification | Not qualified for automotive; lacks guaranteed 200 pF capacitive load drive specification | Prefer for cost-sensitive industrial wireless sensors where automotive qualification is unnecessary |
Compared with LMV712Q1MMX/NOPB, LMV722Q1MMX/NOPB trades shutdown capability for higher speed, while TLV9062IPWR offers lower noise but sacrifices automotive reliability and capacitive drive assurance-making LMV712Q1MMX/NOPB uniquely balanced for RF PA control in harsh environments.

FAQ
What is the maximum capacitive load the LMV712Q1MMX/NOPB can drive without oscillation?
The LMV712Q1MMX/NOPB is specified to drive up to 200 pF in unity-gain configuration without oscillation, verified across –40°C to +125°C and 2.7 V to 5.5 V supply. This capability eliminates external isolation resistors when interfacing with typical PA gate capacitances and RF filter networks, simplifying layout in compact RF modules.
Does the LMV712Q1MMX/NOPB support true rail-to-rail input and output operation?
Yes, the LMV712Q1MMX/NOPB supports rail-to-rail input (V− − 0.2 V to V+ + 0.3 V) and rail-to-rail output (within 12 mV of rails at 10 kΩ load, 50 mV at 600 Ω). This enables direct connection to RF detectors, DACs, and PA bias nodes without level-shifting components-critical for minimizing signal path error in precision envelope control loops.
How does the independent shutdown feature of the LMV712Q1MMX/NOPB benefit RF power amplifier designs?
The LMV712Q1MMX/NOPB's independent SDA and SDB pins allow per-channel shutdown, reducing supply current to ≤1.5 µA per disabled channel and pulling outputs to V−. In GSM/UMTS burst transmission, this enables precise timing of PA activation with glitch-free 2.2 µs turnon-preventing RF output transients that would degrade spectral mask compliance.
Is the LMV712Q1MMX/NOPB qualified for automotive applications?
Yes, the LMV712Q1MMX/NOPB is AEC-Q100 Grade 1 qualified (–40°C to +125°C), with full electrical characterization and reliability testing performed across this range. It is intended for automotive RF subsystems including telematics control units, V2X transceivers, and infotainment cellular modems requiring extended temperature operation and long-term supply stability.
What is the typical input offset voltage specification for the LMV712Q1MMX/NOPB at 25°C?
The LMV712Q1MMX/NOPB has a maximum input offset voltage of 3 mV at 25°C for WSON and VSSOP packages (including LMV712Q1MMX/NOPB), with typical value of 0.4 mV. This low VOS ensures minimal static error in closed-loop PA control, especially important when regulating output power to ±0.5 dB accuracy in cellular base stations and repeaters.
